Application filed December 27, 1916. Serial No. 139,137.

To cZZ whom t may concern.'

Be it known that l, Pn'rnn SOLAINI, a subject or3 the King of Italy,residing at New York city, county and State of New York, have invented anew and useful Lock, of which the following is a specification.

My invention relates to improvements in locks and in the particular formshow'n I have combined both a locking bolt and a latch bolt, the samebeing arranged in a novel manner as hereinafter set forth.

In the accompanying drawings:

Figure 1 shows the invention as applied to the inside of a door and doorcasing, certain parts being removed to show the inmrior arrangement,said view being partly in section on the line 1-1 of Fig. 5.

Fig. 2 is a view of the reverse side of certain parts shown in Fig. l,said parts being in a different position and partly in section on theline 2--2 of Fig. 5.

Fig. 3 is a view similar to Fig. 1, with certain parts removed, theparts illustrated heing shown in a different position.

F ig. 4 is an edge view of the door with the lock thereon.

Fig. 5 is a section on the line 5-5 of Fig. 1.

Fig. 6 is a detail View.

1 represents a door. 2 represents a cas 4.- represents the casing ofwhat l may term the strike or keeper. 5 represents a locking bolt whichis pivoted within the casing 2i and which has a curved endia whichoperates as the bolt proper. tie-G are fixed abutmcnts within the keeperhousing 4. Wvhen the lock bolt is turned. to the position shown `in Fig.3, the door is unlocked. iVhcn, however, the lock bolt is turned to theposition shown in Fig. 1, the door is locked, the bolt end 5n beingswung` around so as to project into the keeper and around the ahntroents(3 6. The end of the bolt 5a is. by preference sullicicntly long so thatit will project back into a cavity in the lock casing as shown in Fig. 1when the door is locked thereby adding greatly to security. 0bviouslythis bolt is ei'ective when applied either to a swinging door or asliding door. lWhen applied to a swinging door the lock may also beprovided with a latch bolt 7, which is suitably mounted in thelockcasing instance the' latch ,bolt 7 is mounted to i'ecij'n'ocaieaiul isnorinally'pmat the back of the lock casing which is connected by a stem10 to the rear end of the latch bolt 'i' so that the latch holt may beretracted by pulling back the finger piece 9 to the dotted line positionshown in Fig. 2. 1l is a` knob at the inner side of the lock case 3, thesame being directly connected in any suitable manner to the swingingdead bolt 5, so that when the knob is turned the said dead bolt will becorrespondingly turned to the locked or the unlocked position. This knob11 has a tubular shank 12. Projecting into the opposite end of thetubular shank 12 is a stem 14 which is mounted at the inner end of the.usual plug 4portion 15 of a pin cylinder lock, wherebyvyieldinglvmounted on the end or" the plug 15 so that it may enter thesleeve 1.2. Without binding. The inner end of the sleeve 12 is cutawayat one side as best seen in Figs. 16 is a pin carried by the stem 111and standing in the out away portion of the sleeve 12the cut awayportion being'sufiicient to permit the stern 14 to be turned freely to alimited extent Without turning the sleeve 12, for the purposehereinafter described. The stein 1.4 may have a series ofholes'toreceive the pin 16 so that .the lock may be applied to doors of diierentthicknesses, the cylinder lock beingjmade suitably adjustable. lf thedoor were thicker than that indicated in Fig. 5, the cylinder lock wouldbe adjusted thereto .and the pin 16 would be screwed into the properhole in the stern 14- so as to position the pin 16 in the cut awayvportionv of the'sleeve 12. 17 is a roll back mounted on the sleeve 12.This roll back faces up with a shoulder 18 on the tail of the latch. 19is a spring that may be located in the lower part of the casing 3 andwhich may frictionally engage a shoulder' 5b on thel 4hooked arm 5a ofthe dead boit in its retracted position, (see Fig. 2) and which 1:1 h ,jl #e salici kaepexz', and menus for inde- @d sy 2;.
